The pigment_pattern works, at least, because it isn't applying a texture within
a texture. The pigment_pattern creates a grayscale pattern (it will convert
normally colored patterns to grays) that the texture map. It's not trying to
undo turbulence, the turbulence isn't applied to the underlying pattern to begin
with.
